Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Rename all files which contain the sub-string 'foo', replacing it with 'bar'

Terminal - Rename all files which contain the sub-string 'foo', replacing it with 'bar'
rename foo bar directory/filename

Rename all files which contain the sub-string 'foo', replacing it with 'bar'

rename command in my system -Fuduntu running 2.6.38 Linux Kernel- is an ELF 64-bit LSB executable, not a Perl script. man page for rename command shows syntax as "rename from to where" (or something like that), so I am doing just what I have been told...


There is 1 alternative - vote for the best!

Terminal - Alternatives
for i in ./*foo*;do mv -- "$i" "${i//foo/bar}";done

That is an alternative to command 8368.

Command 8368 is EXTREMELY NOT clever.

1) Will break also for files with spaces AND new lines in them AND for an empty expansion of the glob '*'

2) For making such a simple task it uses two pipes, thus forking.

3) xargs(1) is dangerous (broken) when processing filenames that are not NUL-terminated.

4) ls shows you a representation of files. They are NOT file names (for simple names, they mostly happen to be equivalent). Do NOT try to parse it.

Why? see this :http://mywiki.wooledge.org/ParsingLs

Recursive version:

find . -depth -name "*foo*" -exec bash -c 'for f; do base=${f##*/}; mv -- "$f" "${f%/*}/${base//foo/bar}"; done' _ {} +
rename 's/foo/bar/g' ./*

Would this command line achieve the desired function? My CLI knowledge is not great so this could certainly be wrong. It is merely a suggestion for more experienced uses to critique. Best wishes roly :-)

ls * | sed -e 'p;s/foo/bar/' | xargs -n2 mv
2011-04-30 00:21:10
User: windfold
Functions: ls sed xargs

Renames all files in a directory named foo to bar.

foobar1 gets renamed to barbar1

barfoo2 gets renamed to barbar2

fooobarfoo gets renamed to barobarfoo

NOTE: Will break for files with spaces AND new lines AND for an empty expansion of the glob '*'

ls | sed 'p;s/foo/bar/' | xargs -n2 mv
for f in *; do mv "$f" "${f/foo/bar}"; done
2011-04-30 09:53:20
User: uwe
Functions: mv

without sed, but has no problems with files with spaces or other critical characters
